Abstract

Polyacetal compositions containing 0.05 to 5 weight percent of an oxo-piperazinyl-triazine hindered amine light stabilizer wherein the hindered N<4> atom in the piperazinone ring of the stabilizer is alkylated with a methyl, ethyl, or propyl group, said compositions being relatively stable upon exposure to UV light. A polyacetal composition containing a specific oxo-piperazinyl-triazine hindered amine light stabilizer wherein the hindered N<4> atom is not alkylated is shown to be relatively stable upon exposure to UV light. Both compositions possess stability during melt processing and do not significantly lose physical properties upon exposure to heat and light.
